[PATCH AUTOSEL 6.18-5.10] platform/x86: dell-laptop: add Inspiron N5110 to touchpad LED quirk table

[Sasha Levin <sashal@kernel.org>]

From: Gleb Sonichev <sonichev555@gmail.com>

[ Upstream commit bfe91a80b13f8068f6fa07aa8c468d284150d4ad ]

The Inspiron N5110 needs the touchpad LED quirk (Vostro V130 quirk)
to properly control the touchpad LED. Add its DMI identifier
to the existing quirk table, next to the similar Inspiron M5110 entry.

Tested on Dell Inspiron N5110.
The touchpad LED works correctly with this quirk enabled.

LLM Generated explanations, may be completely bogus:

The background git searches finished; they don't change the earlier
**YES** verdict.

- **N5110/M5110 grep:** No commit for this N5110 quirk in the tree.
  Broad `--grep="N5110"`/`"M5110"` hits were unrelated (WM5110 codec,
  `dell-wmi` on M5110). The touchpad LED quirk for M5110 is still only
  `2a748853ca395c` (2011).
- **Author search:** Gleb Sonichev has no other commits in this checkout
  — this looks like a one-off hardware report.
- **Similar quirk history:** Found the usual precedent commits
  (`a2174ba29a302` typo fix, `89a8f23fee5ef` Latitude 7520 quirk), which
  matches the established pattern for these DMI table additions.
